PAPER BAG.

Specification of Letters Patent.

Patented Dec. 14, 1909.

To all whom it may concern:

Be it known that I, JOHN Sores, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Paper Bags, of which the following is a specification.

My invention relates to an improvement in paper bags, primarily of that class known as a double bag, in which the inner bag or lining is of moisture proof paper.

The'object of my invention is to provide a paper bag of duplex form, in whlch the blanks of both bags are of the same size and outline, each folded on a transverse line forming the bottom and two sides, with flaps extended from one of their sides and in which the flaps of the inner bag are secured upon the inner surface of its opposing sides, while the flaps of the outer bag are secured upon the outer surface of its opposing side.

Another object of my invention is to provide an end seam bag of duplex form, one bag within the other, and in which the blanks of both bags are of the same marginal outline and dimension.

The features of my invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which Figure 1 is a plan view of the blank of both bags. Fig. 2 is an open end elevation of a completed bag. Fig. 3 is a view of the bag with a portion of the sides and one of the flaps illustrated in unattached position.

The bag is formed of-an outer and inner bag member, each consisting of a blank havin the sides 1, 2, of equal dimension folder? along the usual transverse line 3 in forming the ba The side 1 of each blank is provided with the extended flaps 4. In forming a completed bag, one blank is placed over the other with the sides 1, 2, folded u on themselves, and the flaps 4 of the innerv ag pasted or secured upon the inside surface of the side 2, while the flaps of the outer bag overlap and are asted or secured upon the outer surface of t e outer bag side 2. The edges of the side 2 opposing each other may be secured together along a marginal edge line for maintaining the two bags in position, one within the other, so as to prevent the inner bag from being withdrawn.

By thls construction, the sides 2 of both bags are secured between the flaps of the side 1, as illustrated in Fig. 2, this being the preferred manner of connecting the flaps to the opposing sides of both bags. It is obvious, however, that both bags could be formed in the same manner with their flaps secured to the respective opposing sides of each bag, in the same manner, and the one bag inserted within the other without departing from the features of my invention.

I am aware that bags of this class can be variously formed from different sized blanks or of different marginal outlines, for forming a duplex bag, but the essential feature of my invention is in forming an end seam bag of duplex form, having flaps extended from one of the bag sides, and in which tli blanks of both bags are identically thegame in marginal outline and dimension.

Having described my invention, I claim 1. A paper bag formed of two blanks of the same marginal outline and dimension, each comprising two sides with a medial line of fold formed in the bottom of each.

bag, with the one blank placed over the other, securing flaps extended from one side of each bag and secured upon their respective clpposing sides.

2. paper bag formed from an outer blank and an inner blank, each blank comprising two sides of equal dimensions, with a medial line of fold, securin flaps extendmy hand.
